Indexing error in CTXSYS.INSO_FILTER

Question

hi,
Do you know, how can i correctly creat the index in oracle text? I have created a text table:
CREATE TABLE texttable(text_id int PRIMARY KEY not null, titel varchar2(500), author varchar2(20), datum date, text_size int, text_typ varchar2(10), content CLOB)
I have inserted the documents in content column. text_typ column is the format column (text or binary)help for the filtering. I want to create an index for the column content.
CREATE INDEX oracle_index ON texttable(content) INDEXTYPE IS CTXSYS.CONTEXT PARAMETERS('
DATASTORE CTXSYS.DEFAULT_DATASTORE
FILTER CTXSYS.INSO_FILTER format column text_typ
LEXER oracle_lexer_intern
WORDLIST oracle_wordlist_intern
I get always the erro message:
java.sql.SQLException: ORA-29855: error occurred in the execution of ODCIINDEXCREATE routine
ORA-20000: Oracle Text error:
DRG-11000: invalid keyword CTXSYS.INSO_FILTER
ORA-06512: in "CTXSYS.DRUE", line 157
ORA-06512: in "CTXSYS.TEXTINDEXMETHODS", line 186
I don't understand why inso_filter is an invalid keyword. I have seen the same example for INSO_FILTER in the documentation Oracle Text Reference Release 9.2.
How can I solve the problem? Can you give me any suggestions?
Thank you very much. Greetings from Germany.

Hi roger,
thank you for your help. I think, i am not getting any line-feeds or other funny characters included in my "PARAMETERS" string. I have only set the attributs for lexer and wordlist. It is not a problem with CTXSYS.INSO_FILTER.
For creating the index i have written the following java programm:
public class OracleText_intern {
public Connection connect() throws Exception{
//OCI-Driver is used
//I have used autocommit
public String index_vorbereitung (Connection conn) throws Exception{
CallableStatement cstmt;
Statement stmt = conn.createStatement();
cstmt = conn.prepareCall("{call ctx_ddl.drop_preference(?)}");
cstmt.setString(1, "oracle_lexer_intern");
cstmt.execute();
cstmt = conn.prepareCall("{call ctx_ddl.create_preference(?, ?)}");
cstmt.setString(1, "oracle_lexer_intern");
cstmt.setString(2, "BASIC_LEXER");
cstmt.execute();
cstmt = conn.prepareCall("{call ctx_ddl.set_attribute(?, ?, ?)}");
cstmt.setString(1, "oracle_lexer_intern");
cstmt.setString(2, "base_letter");
cstmt.setString(3, "yes");
cstmt.execute();
cstmt = conn.prepareCall("{call ctx_ddl.set_attribute(?, ?, ?)}");
cstmt.setString(1, "oracle_lexer_intern");
cstmt.setString(2, "index_stems");
cstmt.setString(3, "german");
cstmt.execute();
cstmt = conn.prepareCall("{call ctx_ddl.set_attribute(?, ?, ?)}");
cstmt.setString(1, "oracle_lexer_intern");
cstmt.setString(2, "printjoins");
cstmt.setString(3, "_-");
cstmt.execute();
cstmt = conn.prepareCall("{call ctx_ddl.drop_preference(?)}");
cstmt.setString(1, "oracle_wordlist_intern");
cstmt.execute();
cstmt = conn.prepareCall("{call ctx_ddl.create_preference(?, ?)}");
cstmt.setString(1, "oracle_wordlist_intern");
cstmt.setString(2, "BASIC_WORDLIST");
cstmt.execute();
cstmt = conn.prepareCall("{call ctx_ddl.set_attribute(?, ?, ?)}");
cstmt.setString(1, "oracle_wordlist_intern");
cstmt.setString(2, "stemmer");
cstmt.setString(3, "German");
cstmt.execute();
cstmt = conn.prepareCall("{call ctx_ddl.set_attribute(?, ?, ?)}");
cstmt.setString(1, "oracle_wordlist_intern");
cstmt.setString(2, "fuzzy_match");
cstmt.setString(3, "German");
cstmt.execute();
cstmt = conn.prepareCall("{call ctx_ddl.set_attribute(?, ?, ?)}");
cstmt.setString(1, "oracle_wordlist_intern");
cstmt.setString(2, "substring_index");
cstmt.setString(3, "true");
cstmt.execute();
cstmt = conn.prepareCall("{call ctx_ddl.set_attribute(?, ?, ?)}");
cstmt.setString(1, "oracle_wordlist_intern");
cstmt.setString(2, "prefix_index");
cstmt.setString(3, "true");
cstmt.execute();
String index_str = "CREATE INDEX oracle_index_intern ON texttable_intern(content)" +
"INDEXTYPE IS CTXSYS.CONTEXT PARAMETERS('" +
"DATASTORE CTXSYS.DEFAULT_DATASTORE" +
"FILTER CTXSYS.INSO_FILTER format column text_typ"+
"LEXER oracle_lexer_intern" +
"WORDLIST oracle_wordlist_intern" +
cstmt.close();
return index_str;
public void textmessung(Connection conn, String indexstr) throws Exception {
for(int i=1; i<12; i++){
if (i==1) {stmt.execute(indexstr);}
else {stmt.execute("ALTER INDEX oracle_index_intern REBUILD PARALLEL");}
public static void main(String[] args) throws Exception{
String index_str = ortext.index_vorbereitung(con);
ortext.textmessung(con, index_str);
I can not find the error. Can you still give me little suggestions?
Thank you very much and greeting from germany
